Element #13—Protect On-site Stormwater Management BMPs for Runoff from Roofs <br /> and Other Hard Surfaces <br /> BMPs C233 will be used. On-site stormwater management BMPs used for <br /> runoff from roofs and other hard surfaces include full dispersion, roof <br /> downspout full infiltration or dispersion systems, perforated stubout <br /> connections, rain gardens, bioretention systems, permeable pavement, <br /> sheetflow dispersion, and concentrated flow dispersion. The areas on the site <br /> to be used for these BMPs shall be protected from siltation and compaction <br /> during construction by sequencing the construction in a fashion to install <br /> these BMPs at the latter part of the construction grading operations, by <br /> excluding equipment from the BMPS and the associated areas, and by using <br /> the erosion and sedimentation control BMPs listed below. Additional <br /> requirements for protecting these BMPs during the construction process, <br /> testing functionality, and restoring functionality are needed at the final stage <br /> of the construction process. <br /> Insight Engineering Co. -Stormwater Site Plan 3/25/2021 <br /> - 19- <br />
